Why a Battery Monitoring System (BMS)?
• IEEE –ANSI 1188 recommends battery monitoring
• 80% of businesses require uptime of 99,99%
• Downtime cost is high (datacenter average is 230.000€/hour)
• Increase the life and performance of Batteries
• Reduces operating cost• Monitoring = Sustainable
What do we have to monitor?
• Current and Voltage• Temperature• Internal resistance• Visual : Condition of the battery (no
corrosion, leakage of electrolyte,…)
No BMS vs. BMS….
A Lead Acid (VRLA) Battery Model• There is no standardized battery model…
BMS Operating Principles
• Current, voltage, temperature and internal impedance measurement should be performed for each battery, allowing comparing each battery against the others
• Discharge cycles are counted• Operating time is monitored• Historical data allows battery failure
prediction• Comparative data between batteries of
same system allow battery failure prediction
Wired BMSPermanent wiring between battery measurement modules (BMM) and BMS main unit
Advantages• communication is immune to the
disturbances• BMMs could be powered externally
Drawbacks• important installation costs• limited number of batteries /system• possible failure of communication in case of
cable interruption (single point of failure on each communication cable)
• some are performing only multiple blocks measurement
Wireless BMSNo wiring between battery measurement modules (BMM) and BMS main unit.Communication is performed in RF
Advantages•Very easy and cost effective installation •High number of batteries/ system possible•Overall cost is lower than wired BMS•No need of external power supply for the BMM•Measurement modules are better isolated
Drawbacks•Communication can be affected by heavy shielded environments
Wireless BMS
Wireless BMS• 414 Batteries x 12V 92Ah
